Description

Technical Field

[0001] This utility model relates to the field of smoke detector technology, and in particular to an explosion-proof aspirating smoke detector. Background Technology

[0002] A smoke detector is a device that detects fires early by sensing the smoke generated in the early stages of a fire and sends out an alarm signal. It is an important component of an automatic fire alarm system.

[0003] In existing technologies, the smoke and heat detector with application number CN202322689140.1 uses a through slot, irregular hole, and rotating plate. Using specialized maintenance tools such as an Allen wrench, the detector is inserted into the irregular hole and rotated. Driven by the rotating shaft, the rotating plate rotates. When the rotating plate is parallel to the through slot, pulling the first sleeve separates the detector body from the top cover. This eliminates the need to repeatedly loosen screws, making disassembly simpler and faster than tightening bolts multiple times. Furthermore, the irregular hole design ensures that only qualified personnel can use specialized tools, preventing accidental disassembly by non-maintenance personnel. However, the detector's monitoring area is limited; it cannot detect smoke generated by fires in distant areas in a timely manner, potentially missing the optimal rescue time. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof aspirating smoke detector that can solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an explosion-proof aspirating smoke detector, comprising a detector body:

[0006] A data acquisition component, which is installed on the upper part of the detector body, is used to collect data on the outside air.

[0007] The acquisition component includes:

[0008] A data acquisition tube is fixedly installed on the upper end of the detector body. A connecting tube is fixedly installed on the upper end of the data acquisition tube. A branch tube is fixedly installed on the upper end of the connecting tube. A locking ring is threadedly connected to the outer side of the branch tube. A locking plate is rotatably connected to the upper end of the locking ring. A sealing block is fixedly installed on the lower end of the locking plate.

[0009] In the above scheme, the locking ring is installed on the outside of the branch pipe, and the locking ring is rotated to slide down, which drives the locking plate to slide down, so that the sealing block is embedded in the inside of the branch pipe, thereby sealing the branch pipe and preventing dust and impurities from entering the detector body through the branch pipe.

[0010] A further feature of this invention includes:

[0011] A filter assembly, installed inside the acquisition assembly, is used to filter the extracted air.

[0012] The filtering component includes:

[0013] An empty slot is formed inside the collection tube. A filter frame is slidably connected inside the empty slot. A filter plate is fixedly installed at the bottom of the filter frame. A separator tube is fixedly installed in the center of the filter frame. An adsorption groove is formed inside the filter frame outside the separator tube. A receiving ring is fixedly installed at the upper end of the adsorption groove. A cover plate is snapped onto the upper end of the filter frame. A through groove is formed inside the separator tube.

[0014] In the above scheme, when outside air enters the inside of the collection tube, the filter plate in the filter frame intercepts impurities and dust in the air, preventing dust and impurities from entering the detector body and thus affecting the use of the detector body.

[0015] A further feature of this invention includes:

[0016] A locking component, installed at the rear end of the acquisition component, is used to lock the internal structure of the filtering component.

[0017] The locking component includes:

[0018] A fixing block is fixedly installed at the rear end of the filter frame. A locking block is fixedly installed at the upper end of the fixing block at the rear end of the collection tube. A card block is slidably connected inside the locking block. A spring is provided between the card block and the locking block. A pull rod is fixedly installed at the upper end of the card block. A card slot is opened at the upper end of the fixing block. The rear side of the lower end of the card block is designed with a slope.

[0019] In the above scheme, when the filter frame is inserted into the collection tube, the spring inside the locking block pushes the card block down, causing the card block to engage with the slot on the fixed block, thereby limiting the locking block and locking the filter frame.

[0020] The beneficial effects of this utility model are:

[0021] The acquisition component of this invention, through the cooperation of connecting pipes and branch pipes, facilitates the introduction and installation of multiple corresponding sampling pipes, enabling sampling in multiple areas. This facilitates the introduction of gas from different areas into the detector body, thereby increasing the monitoring range of the detector body. At the same time, the filtration component, through the cooperation of adsorption grooves and filter plates, intercepts dust and impurities in the air and adsorbs moisture in the air, preventing dust, impurities, and moisture from entering the detector body and thus affecting the use of the detector body.

[0022] The locking component of this invention uses a pull rod and a locking block to facilitate the disassembly and installation of the filter frame, the cleaning of the filter plate, and the replacement and cleaning of the silica gel desiccant inside the adsorption tank. This prevents moisture buildup in the silica gel desiccant from affecting the subsequent use of the detector body after prolonged use. Attached Figure Description

[0031] Reference Figure 1-5An explosion-proof aspirating smoke detector includes a detector body 1, a data acquisition component 2, a filter component 3, and a locking component 4. The data acquisition component 2 is installed on the upper end of the detector body 1 and is used to collect outside air. The filter component 3 is installed inside the data acquisition component 2 and is used to filter the extracted air. The locking component 4 is installed at the rear end of the data acquisition component 2 and is used to lock the internal structure of the filter component 3.

[0032] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The acquisition component 2 includes: an acquisition tube 201 fixedly installed on the upper end of the detector body 1; a connecting tube 202 fixedly installed on the upper end of the acquisition tube 201; a branch tube 203 fixedly installed on the upper end of the connecting tube 202; a locking ring 204 threadedly connected to the outside of the branch tube 203; a locking plate 205 rotatably connected to the upper end of the locking ring 204; and a sealing block 206 fixedly installed at the lower end of the locking plate 205. The filter component 3 includes: a slot 301 opened inside the acquisition tube 201; a filter frame 302 slidably connected inside the slot 301; a filter plate 303 fixedly installed at the bottom end of the filter frame 302; a partition tube 304 fixedly installed in the center of the filter frame 302; an adsorption groove 305 opened inside the filter frame 302 outside the partition tube 304; a receiving ring 306 fixedly installed at the upper end of the adsorption groove 305; a cover plate 307 snapped onto the upper end of the filter frame 302; and a through groove 308 opened inside the partition tube 304.

[0033] In this invention, when using the detector body 1, sampling tubes are installed according to the area to be sampled. The locking ring 204 on the branch pipe 203 is rotated. As the locking ring 204 spirals upward, it drives the locking plate 205 upward, thereby disengaging the sealing block 206 from the branch pipe 203, releasing the seal on the branch pipe 203. The locking ring 204 is then unscrewed from the branch pipe 203. The sampling tube is then inserted into the branch pipe 203. The detector body 1 is activated to draw air from the sampling tube into the connecting pipe 202, and then into the detector body 1 through the collection tube 201, thus detecting the fire. Multiple corresponding sampling tubes can be introduced into the branch pipe 203 to achieve multi-area sampling, facilitating the introduction of gas from different areas into the detector body 1 and improving the detector's performance. The main body 1 has a monitoring range, and the idle branch pipe 203 is sealed by the sealing block 206 to prevent dust and impurities from entering the detector body 1 through the branch pipe 203. When outside air enters the detector body 1 through the collection pipe 201, the filter plate 303 inside the filter frame 302 intercepts dust and impurities in the air to prevent them from entering the detector body 1 and affecting its use. The adsorption tank 305 is filled with silica gel desiccant. The through groove 308 opened inside the separator pipe 304 allows the air passing through the collection pipe 201 to enter the adsorption tank 305, so that the silica gel desiccant adsorbs the moisture in the air and prevents moisture from entering the detector body 1, thus affecting the accuracy of the detector body 1 in detecting flue gas.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The locking component 4 includes: a fixing block 401 fixedly installed at the rear end of the filter frame 302; a locking block 402 fixedly installed at the rear end of the collection tube 201 at the upper end of the fixing block 401; a locking block 403 slidably connected inside the locking block 402; a spring 404 provided between the locking block 403 and the locking block 402; a pull rod 405 fixedly installed at the upper end of the locking block 403; a slot 406 opened at the upper end of the fixing block 401; and a beveled design at the rear side of the lower end of the locking block 403.

[0035] In this utility model, when the filter assembly 3 needs to be disassembled and cleaned, the pull rod 405 is pulled upward, causing the locking block 403 inside the locking block 402 to slide upward and press the spring 404, so that the locking block 403 disengages from the slot 406 on the fixing block 401, releasing the locking of the fixing block 401. Then, the fixing block 401 is pulled backward, causing the filter frame 302 to be disassembled from the empty slot 301 on the collection tube 201, and the filter plate 303 on the filter frame 302 is cleaned. Then, the cover plate 307 is pulled up, so that the cover plate 307 is disengaged from the filter frame 302 and from the receiving ring 306. Then, the silica gel desiccant inside the adsorption tank 305 is replaced and cleaned to avoid moisture accumulation in the silica gel desiccant after long-term use, which would affect the subsequent use of the detector body 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
